What red light therapy is
Red light therapy uses low levels of visible red and near-infrared light, delivered to the skin over a set period. It is not a laser treatment in the sense people usually mean, and it is not designed to heat, resurface or remove anything. The light is gentle, the sessions are comfortable, and there is no recovery time to plan around.
At Celtic Lasers, red light therapy uses three wavelengths: 550, 650 and 800 nanometres. Different wavelengths reach to slightly different depths in the skin, which is why devices combine them rather than relying on one.
What it may help with
Red light therapy supports the skin's natural healing process. In practice, that means it may help calm inflammation, reduce temporary redness and support overall skin wellness. People often use it when their skin feels reactive or tired, or as a way to support the skin alongside other treatments.
Notice the word may. Skin responds individually, and red light therapy is a supportive treatment rather than a corrective one. It works best when you think of it as looking after your skin, not as fixing a specific problem in a set number of sessions.
What it will not do
It will not remove hair. That is what laser hair removal is for, and the two treatments work in completely different ways.
It will not resurface skin or remove pigmentation the way laser skin rejuvenation is designed to. If the concern is sun damage, brown spots or visible vessels, laser skin rejuvenation is the treatment built for that, and it needs its own assessment.
It will not tighten skin or change its structure in the way more intensive treatments are designed to. If firmness or texture is your main concern, that is a conversation about options such as microneedling, which works on a different principle entirely, rather than more sessions of red light.
It will not replace a consultation with an appropriate medical provider for a skin condition that needs a diagnosis. Red light therapy is an aesthetic, supportive treatment. If something about your skin is new, changing or worrying you, that is a conversation for a medical professional first.
And it will not produce dramatic overnight change. Anyone promising that from red light therapy is selling the device, not describing it.
Standalone, or as an add-on
Red light therapy can be booked on its own, or added to another treatment. As an add-on, it fits naturally alongside treatments like facials, where the goal is overall skin health. Whether it makes sense for you, and how often, is something to settle at your consultation rather than guess at from a menu.
What a session is like
You lie comfortably while the light is positioned over the treatment area. Most people describe it as gentle and warm at most. Protective eyewear is standard. Because there is nothing to recover from, it slots easily into a day.
How it is priced
Red light therapy is not priced in advance at Celtic Lasers. The plan, and the number of sessions that makes sense, depend on your skin and your goals, so the price is set at the consultation. Packages may be available for services that work best as a series.
Questions worth asking before you book
“What exactly do you expect this to help with, for my skin?” The answer should be specific and modest. Broad promises are a warning sign.
“Is this the right treatment, or is something else a better fit?” A good provider will tell you when laser rejuvenation, a facial or a visit to a medical provider would serve you better.
“How many sessions, and how far apart?” Ask before you buy anything, so the plan is clear from the start.
Who it tends to suit
Red light therapy tends to appeal to people who want to support their skin without downtime, and to people whose skin feels reactive, tired or in need of calming. Because the sessions are gentle, it is often a comfortable starting point for someone who is new to aesthetic treatments and not ready for anything more involved.
It is less suited to people looking for a specific, visible correction, such as removing a brown spot or reducing unwanted hair. For those goals, a treatment designed for that outcome will serve you better, and a good provider will say so rather than sell you sessions of something gentler.
How it fits alongside other treatments
One of the most practical uses of red light therapy is as a supporting step within a wider plan. Paired with a customized facial, for example, it can be part of a session focused on overall skin health. Used this way, it is not doing the main work; it is supporting the skin around the treatment that is.
What matters is that the combination is chosen for your skin, not added by default. If a menu adds red light to everything, it is worth asking what it is adding in your case.
How often people book it
Because red light therapy is supportive rather than corrective, it is usually thought of as a series or an ongoing part of a routine rather than a single appointment. How often makes sense depends on what it is being used for and whether it is standalone or paired with another treatment. That is a question for your consultation, where the plan can be set around your skin rather than a generic schedule.
Red light therapy or laser skin rejuvenation?
The two are often confused because both use light and both are aimed at the skin. They are built for different jobs.
Laser skin rejuvenation at Celtic Lasers uses the Elite iQ Pro, a laser device, and it is designed for specific visible concerns: the appearance of sun damage, brown spots, uneven pigmentation, facial redness and certain visible vessels. It is a corrective treatment, it needs a careful assessment of whether a particular spot or vessel is appropriate for laser, and the plan and price are set at the consultation.
Red light therapy is gentle and supportive. It does not target individual spots or vessels, and it is not designed to change pigmentation. Where rejuvenation is aimed at a specific concern, red light is aimed at the overall condition of the skin.
For some people the right answer is one, for some the other, and for some a plan that uses both at different times. That decision depends on what you want to change and what your skin can comfortably take, which is why it belongs in a consultation rather than on a menu. More detail on the corrective option is in our guide to laser skin rejuvenation.
Where this leaves you
Red light therapy is at its best as a gentle, supportive part of looking after your skin, and at its worst when it is sold as a fix for everything. Go in expecting support rather than transformation, and ask what it is meant to do for you specifically. For more detail, see red light therapy at Celtic Lasers.
